ADOLPHUS S. GOODItIOI-I, OF NEW YORK, N. Y., ASSIGNOR OF ONE-HALF TOJOHN J. MOORE, OF SAME PLACE.

COMBINED RULER AND CALENDAR.

SPECIFICATION forming part of Letters Patent No. 365,916, dated July 5,1887.

Application filed March 23, 1887. Serial No. 232,060. (No model.)

of New York city, New York, have invented a new and useful Improvementin a Combined Ruler and Calendar, of which the following is aspecification.

My invention consists of a calendar" baseplate, made of wood or otherapproved material, in suitable length, breadth, and thick- IO mess toserve for a ruler, and having a channel-way along one side, in which thecalendar, printed on a strip of cardboard or equivalent material, isinserted and retained for use, and is removable for renewal when itsperiod has passed, all as hereinafter fully described, ref erence beingmade to the accompanying drawings, in which Figurelis a plan view of theside of the de vice, showing the calendar. Fig. 2 is a plan view of theother side, and Fig. 3 is an end view.

I take a long narrow and thin strip or bar, a, of wood, rubber, or otherapproved matcrial suitable for a ruler, and make a'chanchannel-way, asshown, said strip being of such breadth and thickness as will bind it inthe groove with sufficient friction to hold it securely during theperiod of its use, but will 55 allow it to be drawn out freely when itsperiod has expired and another is to be substituted. For large anddistinctly-visible figures of the calendar I prefer to use the wholelength for an annual calendar; but in a bar of sixteen 0 inches, orthereabout, a biannual calendar of sufficient elearucss may be employed.I intend to print both sides of the strips consecutively, so that onerenewal may be had by reversing the strip. Afterward a new strip 4 5printed for the succeeding periods is to be substituted. The names ofthe months may be printed on the card strips along with the numbers ofthe days in the common way; but as the names do not require to bechanged I pre fer to print them on one of the margins of the bar, asrepresented in Fig. 1, in order to utilize all the space of the cardstrip for larger and more conspicuous numbers. They may be burned in orimpressed with dies, so as not to be rubbed or worn off by the ab asionto which the surface is exposed. The card strips are not exposed towear, by reason of the channel being considerably deeper than thethickness of the card. I make a bevel-edge, f, on the back and mark ascale of measure thereon, as 6) is usual in rulers of common form, andthus provide a combined tool or instrument comprising a calendar, ruler,and measure, in which the ruler serves for one of the elements of the'calendar-viz., the base-plate-andl said baseplate ofthe calendarconstitutes the ruler, all in one-device, affording greater conveniencethan two separate devices, and avoiding the duplication of parts.necessary when made separately.

I am aware that a calendar has been fastened on the surface of a thinplate, and I am also aware that a ruler has been made with a chain berhaving a sliding cover to contain pencils, and make no claim for suchdevices.

hat I claim, and desire to secure by Let-- tersPatent, is-

l. The improved calendar consisting of the channeled and grooved baseplate or bar and the card-board calendarstrip, said strip being 8cinserted in the channeled groove below the surface of the bar,substantially as described.

2. The improved calendar consisting of the channeled and grooved baseplate or bar, having the names of the months along one of the margins ofthe channels, and the card-board calendar-strip having the numbers ofthe days of the months correspondingly printed on it, substantially asdescribed.
